Abstract
This paper describes a few aspects of a system for expressive, rule-based modifications of audio recordings regarding tempo, dynamics and articulation. The input audio signal is first aligned with a score containing extra information on how to modify a performance. The signal is then transformed into the time-frequency domain. Each played tone is identified using partial tracking and the score information. Articulation and dynamics are changed by modifying the length and content of the partial tracks. The focus here is on the tempo modification which is done using a combination of time frequency techniques and phase reconstruction. Preliminary results indicate that the accuracy of the tempo modification is in average 8.2 ms when comparing Inter Onset Intervals in the resulting signal with the desired ones. Possible applications of such a system are in music pedagogy, basic perception research as well as interactive music systems.Keywordsautomatic music performanceperformance rulesanalysis-synthesistime scale modificationaudio signal processing
